Safety Instructions
Your Oki printer has been carefully designed to give you years
of safe, reliable performance. As with all electrical equipment,
however, there are a few basic precautions you should take to
avoid hurting yourself or damaging the printer:
• Read the setup instructions in this handbook carefully. Be
sure to save it for future reference.
• Read and follow all warning and instruction labels on the
printer itself.
• Unplug the printer before you clean it. Use only a damp
cloth; do not use liquid or aerosol cleaners.
• Place your printer on a firm, solid surface. If you put it on
something unsteady , it may fall and be damaged; if you place
it on a soft surface, such as a rug, sofa, or bed, the vents
may become blocked, causing the printer to overheat.
• To protect your printer from overheating, make sure all
openings on the printer are not blocked. Do not put the printer
on or near a heat source, such as a radiator. Keep it out of
direct sunlight. Allow enough space around the printer for
adequate ventilation and easy access to the paper trays.
• Do not use your printer near water, or spill liquid of any
kind into it.
• Be certain that your power source matches the rating listed
on the back of the printer. If you are not sure, check with
your dealer or with your local power supplier.
• Your printer has an earthed, 3-pin plug as a safety feature,
and it will only fit into an earthed outlet. If you can not plug
it in, you probably have an older , non-earthed outlet; contact
an electrician to have the outlet replaced. Do not use an
adapter to defeat the earthing.
• This printer must be installed near to a power outlet switch
which shall remain easily accessible.
• T o a v oid damaging the po wer cable, do not put anything on
it or place it where it will be walked on. If the cable becomes
damaged or frayed, replace it immediately.
• If you are using an extension cord or power strip with the
printer, make sure that the total of the amperes required by
all the equipment on the extension is less than the extension’ s
rating. The total ratings of all equipment plugged into the
outlet should not exceed 15 amperes.

Important Wiring Instructions
• Do not poke anything into the ventilation slots on the printer;
you could get a shock or cause a fire.
• Aside from the routine maintenance described in this
handbook, do not try to service the printer yourself; opening
the cover may expose you to shocks or other hazards.
• Do not make any adjustments other than those outlined in
the handbook you may cause damage requiring extensive
repair work.
• If anything happens that indicates that your printer is not
working properly or has been damaged, unplug it
immediately and contact your dealer.
These are some of the things to look for:
• The power cable or plug is frayed or damaged.
• Liquid has been spilled into the printer, or it has been
exposed to water.
• The printer has been dropped, or the cabinet is damaged.
• The printer does not function normally when you are
following the operating instructions.
The wires in the power cable are coloured in accordance with
the following code:
Green and Yellow.......Earth
Blue ............................. Neutral
Brown ......................... Live
If the colours of the wires in the power cable of this printer do
not correspond with the markings of the terminals of your plug,
proceed as follows:
• Green and Y ello w must be connected to the terminal marked
with the letter E (or the safety earth symbol) or the terminal
coloured Green or Green & Yellow.
• Brown must be connected to the terminal marked with the
letter L or coloured Red.
• Blue must be connected to the terminal marked with the
letter N or coloured Blue or Black.
Warning: This printer must be earthed.
If you are in any doubt regarding the wiring, please contact a
qualified electrician.

Toner Cartridg e Life
Replacing T oner Cartridge
T oner cartridge life depends on the page density, the percentage
of each page that is printed black. An average business letter is
printed at between 3% and 5% density , graphics density is usually
higher. The higher the print density, the more toner is used. On
the average, a toner cartridge will produce approximately 5000
sheets at 5% print density.
The first toner cartridge you place in your printer will produce
between 2500 and 3500 sheets. This is normal, as the new image
drum reservoir and dev eloping roller system must saturate with
toner.
When to Replace the Toner Cartridge
Replace the toner cartridge after TONER LOW displays in the
control panel window . After TONER LO W displays, the printer
will print 100 more sheets, then display TONER EMPTY and
stop printing. Printing will resume when a new toner cartridge
is installed.
1. Press the access cover release button and raise the access
cover to the vertical position.
WARNING
Some metal surfaces around the fuser area are
hot. These are clearly marked. Do not touc h them.
2. Move the toner cartridge tab towards the front of the
printer to release and close the toner cartridge, and lift
the cartridge out of the printer.

Cleaning the LED Array
3. Shake the new toner cartridge to distribute the toner . Then
remove the packaging.
4. Carefully peel off the sealing tape.
5. Insert the cartridge into the printer.
6. Push the toner cartridge tab towards the rear of the printer
to release the toner into the toner hopper.

Clean the LED array each time you install a new toner cartridge.
A dirty LED array could cause faded vertical areas or light
printing down a page.
1. Remove the LED lens cleaner pad (included with the
Toner Kit) from the package.
2. Locate the LED array (1) on the underside of the printer
cover.
3. Carefully run the cleaner pad across the LED array.
Discard the pad. Close the printer cover.
Note: Extra LED cleaning pads are provided with each toner
cartridge. Clean the LED array between toner changes
if faded vertical stripes appear.

Image Drum Cartridge Life
The life of the image drum depends on a number of factors,
including the operating temperature, humidity , the type of paper
you use, and the number of pages per job. Each time you print or
power on/off, the drum has to rotate to start up and to wind do wn.
As a result, frequent one page print jobs will wear down your
drum more quickly than multiple-page print jobs. The image
drum cartridge should last approximately 19,000 pages at 3 pages
per job, or up to 30,000 pages if you print mostly larger jobs.
When to Replace the Image Drum Cartridge
When the image drum reaches 90% of its life, the CHANGE
DRUM message will display in the control panel window.
Change the image drum cartridge when the print becomes faint
or begins to deteriorate. Ideally you should keep a new cartridge
on hand.
Replacing the Drum Cartridge
Precautions:
The image drum is fragile. To avoid damage to the new
drum, take these precautions while handling the new
image drum cartridge:
• Do not touch the green drum surface.
• Do not set the cartridge down on anything that might
scratch the surface of the drum.
• Do not expose the drum to direct sunlight and do not
expose it to room light for more than 5 minutes. Leave it
in the package until you are ready to install it into the
printer.
1. Press the OPEN button and lift the cover.

Fonts
What Is a Font?
Strictly speaking, a font refers to a set of printable characters in
a particular typeface of a specific size (e.g. 12 point) and style
(e.g. roman, bold or bold-italic). In computer printing, howev er ,
this term has been used in a wider context to refer to all sizes
and styles of a particular typeface. In printers, fonts may be
divided into two basic types: bitmap fonts and scalable (or
outline) fonts.
Bitmap fonts are made up of a pattern of dots (at the printer
resolution) to form the image of each printable character. These
are of a fixed size, and scaling makes them look ragged.
Scalable fonts are stored as a set of mathematical curves. At
print time the printer uses the stored curves to make up a bitmap
of each character required, at the required size, and in the required
style, at the full printer resolution. Such fonts are therefore said
to be scalable, and do not appear ragged at enlarged sizes.
Your printer has 48 built-in fonts as standard, including 35 HP
LaserJet 4 compatible Intellifont (scalable), 10 TrueType
(scalable), and 3 bitmapped fonts.
Printing a Font List
1. Press the ON-LINE button to take the printer off line.
2. Press the TRAY TYPE/Print Fonts button for at least
two seconds.
3. After a short delay two pages of font information will be
printed, including samples.
Using Fonts
Some MS-DOS and most Windows programs provide an easy
method of font selection within documents. In these cases the
printer’s font selection is controlled by the host PC software
application (or by W indo ws itself). On other software platforms
special codes (escape sequences) must be embedded with the
print data. This topic is beyond the scope of this Help Guide.
Howev er, the font list referred to in the pre vious topic contains a
list of the required codes. Use of these codes is best left to a
professional programmer.

jam:
INPUT JAM Paper has failed to leave the selected tray and
enter the printer’s internal paper path.
FEED JAM Paper has entered the printer b ut failed to reach
the exit.
EXIT JAM Paper has reached the exit but has failed to
exit completely from the printer.

The printer will warm up and commence printing when

The normal paper path from a main paper tray to the top output
stack involv es two complete U-turns. This may sometimes cause
very heavyweight paper or cardstock to jam or misfeed.
Use the front tray to feed this type of paper and the rear paper
exit to collect your printed output. This gives a nearly straight
paper path through the machine, and may prove more reliable in
this type of application.
Print Quality Adjustments for Different Paper
The process used to fuse (fix) the printed image to the paper
involv e a mixture of pressure and heat. Too much heat will cause
lightweight paper to crease or curl, while too little heat will cause
the image not to fuse fully into heavyweight paper.
Use the MEDIA TYPE setting in MENU 1 (page 12) to adjust
for different thicknesses of paper.

Paper Size Check Messages
Printer Output Garbled
When feeding paper from the first or second (optional) paper
tray , the printer checks the size setting of the paper loaded there
against the page size requested by your print data. If the two do
not match, the printer pauses and displays a PAPER SIZE
CHECK message. Load the correct size of paper and then press
Recover for at least two seconds to resume printing.
If you do not wish to change the paper, you may simply press
Recover to resume printing.
If you wish the printer to omit these checks altogether:
1. Press ON LINE so that the display reads OFF-LINE.
2. Press MENU 1 repeatedly until PAPER SIZE CHECK
is displayed.
3. Press so that the display reads DISABLED.
4. Press ENTER to confirm your selection.
5. Press ON LINE so that the display reads ON-LINE.
If the output of your printer appears to be corrupted, there are
two possible causes: either the cable connection to your computer
is bad, or the data generated on the computer is not correct for
the printer.
Probably the easiest item to check first is your data cable. This
should be securely connected at both ends, and locked into place
with the connector hardware. The total cable length should ideally
be no longer than about 1.8 metres. If you use a mechanical
switch to share the printer between multiple users, the switch is
usually equivalent to about 30cm of cable.
If the cable connection appears to be satisfactory and your
computer application software is functioning normally, try
reinstalling the printer driver software supplied with your printer .
If you are still unable to resolve the problem, your Oki dealer
may be able to help you.
Printable Area
The printable area is the area inside the overall dimensions of
the page on which the machine can pr int. This is normally 0.64cm
in from each edge for each size of paper supported. Windows
applications will normally take this into account provided you
have installed the appropriate Oki supplied printer driver.

Troubleshooting Software with Hex Dump Mode
Clearing a Print Job
This mode is provided for programmers and other technical users
with a knowledge of hexadecimal notation. In this mode the
printer does not interpret codes and strings received, b ut instead
prints all bytes received in ascii-hex notation.
For example, the string:
ABCDEF
GHIJKL
will result in:
41 42 43 44 45 46 0D 0A 47 48 49 4A 4B 4C
being printed.
To enter Hex Dump mode:
1. Hol d down the MENU 1 button while switching the
printer ON.
2. Continue to hold the MENU 1 button until the message
USER MNT appears.
3. Press MENU 1 twice, so that HEX DUMP appears.
4. Press ENTER to make your selection.
If, following an interruption, you wish to clear a print job instead
of completing it, press Reset for at least two seconds.
This will cause all settings to return to current user defaults
and any data in the buffer but not yet printed to be discarded.
To exit Hex Dump mode, switch the printer OFF.

Image Drum Cleaning
If your printer shows signs of fading, streaking or erratic marks,
you may be able to clear the problem by generating a drum
cleaning page as follows:
1. Press the ON-LINE button to take the printer off line.
2. Hold down the buttons together for at least two
seconds.
The display will show DRUM CLEANING PAGE and
MANUAL A4 SIZE REQUEST.
3. Pull down the manual feed tray (1) and unfold the tray
extension.
1
4. Insert a sheet of A4 plain paper into the manual feed
tray.
5. Press the FORM FEED button.
The display will show DR UM CLEANING as the paper
is fed. The paper will emerge from the printer with grey
shading. This sheet may be discarded.
6. Return the printer on line by pressing the ON-LINE
button.
If subsequent printing appears faded or uneven, try replacing
the toner cartridge.

31Help Guide
Memory Options
Your printer comes with 2 MBytes of random access memory
(RAM) fitted as standard. Upgrade options are av ailable through
your Oki dealer in a range of memory sizes from 2 MBytes up to
64 MBytes.
These come as SIMM (Single Inline Memory Module) packages,
which may be installed onto the main system board in your
printer.
For complex printing jobs at high resolution, you may require a
memory upgrade. For example, a full page of image data requires
four times as much memory at 600 dpi than for the same image
at 300 dpi.
A PostScript board is also available for your printer.
Menu settings are stored in a special type of memory called
EEPROM (Electrically Erasable Programmable Read-Only
Memory). This type of memory stores information even when
power is removed, b ut may still be updated when menu settings
are changed.
